PLOW.

following is a specification.

My invention relates to plows for making furrows in the land, and itsobject is to generally improve implements of this kind whether they are,used for making a bed for seeds, covering the same, hilling up theearth to crops, laying out lines for plant ing, or for other purposes.

My invention has for its principal object to improve the construction ofthe plow shown and described in the patent to W. T. Huggins, N 0.782,658.

The particular purpose of my invention is to provide a constructionwherebythe digging action of the plow may be varied while stillpreserving a uniform depth of the furrow.

Other objects and the novel features of my invention will be apparentfrom the following, description taken in connection with the drawing, inwhich:

Figure 1 is a View showing so much of a plow or cultivator as isnecessary to show my invention; Fig. 2 is a rear view of the parts ofthe plow shown in Fig. 1; Fig. 3 is a front view of the parts of theplow shown in Fig. 1, the beam being shown in section; and Fig. a is aperspective view of the lower parts of the plow below the section line3-3 in Fig. 1.

Referring to the drawing, the numeral 1 designates the plow orcultivator beam and may be provided with the usual handles (not shown)at the rear end.

Numeral 2 designates the front plow standards to which the plow sweep orshovel (not shown) is to be fastened inthe usual or any suitable way.The said standard 2 is made of two pieces of iron of the proper sizebent into a crescent shape so that the top part of each piece willextend above and forwardly of the beam 1. The two piecescomprising thefront standard 2 are so designed that the upper end will always be asfar forward as the bottom end of the standard.

The numeral 3 designates a metal member .bent at a point intermediateits ends so that one part will be horizontal and the other part willextend upwardly to the Specification of Letters Patent.

beam. The upwardly extending part of the member 8 constitutes'the rearstandard of the plow while the horizontally extending part constitutesthe bottom or runner of ie plow to which the slide i is fastened. Theupwardly extending part or rear standard is bifurcated at the top so asto straddle or embrace the plow beam 1. The arms comprising thebifurcated end of the rear standard are secured to the beam 1 by thebolt 8, the said arms having a series of adjusting holes 9, 9 to receivethe bolt which passes therethrough and through a hole in the beam.

The slide or shoe 4: of the plow has two holes therein to receive bolts12, 12 for securing it to the runner or horizontal portion of the part3. The holes in the runner and in the slide or shoe are the samedistance from each end and so arranged that the slide or shoe may bereversed to allow the shoe to be turned end for end so that the oppositeends can be worn down an equal amount.

The pieces comprising the front standard are bent outwardly as shown inFig. 3 to provide the shoulders 21 and 22 in each of the pieces. Thebeam 1 fits between the shoulders and may rest on the shoulders 21, 21.Above the shoulders 22, 22 in the plates comprising the front standard 2is a series of holes 11 to receive the adjusting bolt 6 which has alever nut 5 attached thereto 50 that the front standard can be tightlyclamped in place at its adjusted position. Any adjustment of the plow asto forward or backward movement to throw more or less earth may besecured by simply loosening the bolt 6 by operating the lever nut 5 andmoving the upper ends of the pieces comprising the standard 2 backwardor forward to the desired position and again fastening the frontstandard in place by turning the lever nut 5.

.The pieces comprising the front standard 2 are pivotally connected attheir lower end to the front end of the runner portion of the part 3 bymeans of the bolt 7 In order to more securely clamp the front standardin place I provide a bolt 10 which extends through the pieces comprisingthe front standard a short distance below the shoulders 21, 21.

The operation of the device will be apparent from the foregoingdescription. When it is desired to adjust the blade or shovel of theplow which is carried by the front standard 2, the lever nut 5 isunscrewed a few turns and the front part of the standard 2 is moved toany position depending upon the angle and digging position desired andthen the standards are fastened by tightening the lever nut 5. As thebeam requires no hole or series of holes through tionv of the frontstandard will maintain the a depth of plow constant. It will be noticedthat the rear standard, when it is adjusted in place, is freelyswingable abouta fixed point in the rear standard and in the beam sothat it and the beam will assume the proper relation to keep the depthof cut constant; Since the standard 2 is adjustable when the top part ismoved forward, it will set theplow point so that it will have a greaterdigging action, that is, it will be at a greater inclination to theearth. When the upper ends of the bars comprising the front standard areadjusted and moved rearwardly the plow point will be set so as tohavea Ilesser digging action since the inclination of the bars will not be sosteep. The variation of the digging action of the plow point will a notalter the depth of plowing since the runner part 3 is pivotallyconnected to the standard and to the beam 1,. and is free to assume sucha position-that the depth will remain constant because the forward endof the beam will be depressed when the upper end ofthe standard is movedforward and the forward end of the beam will be elevated when the upperend of the standard is moved rearwardly. Thus the depth ofplowing willbe kept .constant by the changein the posi tion of the forward end ofthebeam.

It will be noticed that the standard of the plow is curved into acrescent shape thereby shedding any trash or litter that may be plowedthrough.

\ Having thus described my invention, what I claimras new, and desire tosecure by Letters Patent is 1. In a plow, the combination of a plowbeam, a standard having an upper end adjustably connected with the beam,a runner pivotally connected with the foot of said standard and havingits rear end pivotally connected with the beam, the runner "being freelyswinga-ble about a fixed point in the beam, and in the rear end of therunner,

whereby when the upper end of said stand ard is moved forwardly thefront end of the beam is depressed andwhen the upper end of saidstandard is moved rearwardly the front end of the beam is elevated, thuschanging the digging action of the plow but preserving the depthuniform.

2. In a plow, the combination of a plow beam, a standard havingforwardly curved arms embracing the beam and projecting above the same,an adjusting bolt connecting the arms above the beam, a runner pivotallyconnected with the foot of thestandard, the rear end of said runnerextending upwardly and being pivotally connected to the beam by all-shaped connection,'the construction being such that when'the arms ofthe standardare moved forwardly, the front end of thebeam will bedepressed and when moved rearwardly, the front end of the beam will beelevatedthus changing the digging action of the plow but preserving thedepth uniform, the runner being freely swingable with relation to thebeam about arfixed point in said U- shaped connection and in said beam.

3. In a plow, the combination of a plow beam, a front standardcomprisinga pair of forwardly curved arms embracing the beam, extendingabove the same, and each having bolt holes above the beam, an adjustingbolt fitting the bolt holes and connecting the arms above the beam,adevice pivotally connected at its forward end to the foot of the-frontstandard and having a horizontal and rearwardly extending part and anupwardly extending part, the rearwardly extending'part constituting therunner of the plow, the upwardly extending part constituting therearstandard and being bifurcated at its upper end to'embrace the plow beam,means for adjustably'connecting the rearstandard to said beamcomprisingbolt holes in each of said parts of the bifurcated portion, and a boltfitting said last mentioned bolt holes, the upwardly extending part ofsaid device which constitutes the rearstandard when adjusted in placebeing swingable about a fixed point inthe rear standard and in the beamof the front standard are moved forwardly the'front of the plow beamwill be depressed, and when the said arms are moved rearwardly the frontof the beam'will be elevated thereby changing the digging action of theplow, but preserving the depth uniform.

4:. 111a plow, the combination of a plow beam, a front standardcomprising a pair of forwardly curved arms having bent parts near theirupperends providing shoulders toengage the lower edge of said beam, saidarms extending above the beam and each having bolt holes in the partthereof above the beam, an adjusting bolt fitting the bolt extendingpart constituting the rear standard, the said upwardly extending partbeing bifurcated at its upper end to embrace the plow beam and pivotallyconnected to said beam and swingable about a fixed point in the rearstandard and in the beam, for the purpose described.
